English is the canonical source language. UI translations are distributed through WordPress.org language packs when available. Translation files are not bundled in this plugin package.
Headings, body text, and button labels are content, not UI strings, and may be written in any language. The per-slider language setting sets the wrapper lang attribute and selects right-to-left direction for Arabic, Hebrew, Persian, and Urdu.
This release does not contain an AI content-generation feature. No AI language-support claim applies.
